Description

Two-way double-sided electrical connector

The present invention relates to an electrical connector, and more particularly to a bidirectional double-sided electrical connector.

As the functions of various electronic products are becoming more and more powerful, and handheld devices are becoming more and more popular, there are more and more signal transmission requirements among various products or devices. Among them, signal transmission between the devices is through a signal interface. And proceed. The signal interface is, for example, an electrical connector or a complementary electrical connector that interfaces with it, wherein the electrical connector is an electrical receptacle and the complementary electrical connector is an electrical plug.

Before the electrical connection plug and the electrical connection socket are docked, the electrical connection plug must be oriented in the correct direction toward the electrical connection socket, so that the two can be docked, that is, the electrical connection socket has a plug-in directionality, which is commonly known as a foolproof Function, this function is to ensure that the connection interface on the electrical connector plug can be in contact with the contact terminals on the electrical connection socket. However, most users do not have the habit of connecting the electrical connection plug in the correct direction toward the electrical connection socket. This foolproof function causes the electrical connection plug to fail to connect with the electrical connection socket, and then the user flips the electrical connection plug again to be properly docked. . In other words, this foolproof function causes confusion for the user.
